I couldn't agree more about the nature of a successful classroom setting.
I always try to reinvent myself and not follow old patterns. A classroom is never a one-size-fits-all.
However, there are times when being nice and creative is not enough. Especially if there are (and there are) students that for some reasons learned that in order to succeed, all they have to do is please their teachers.
At some point the instructor must reflect not only a flexible and knowledgeable academic authority but also a metaphor for the industry.
Students in a trade school setting must understand that the industry will not wait for them, so along with being respectful, cheering, and attentive, an instructor must be able to demonstrate a reflection of the real world to the students. Especially the ones that are still not ready to face the real world.
In my experience I found that I sometimes needed to "get down to business" and give a, perhaps cold, reality slap..
What do you people think?
